Abstract—In this work we fabricated STS430L-TiCxNy composites by spark plasma sintering. As sintered STS:TiCxNy samples were annealed at 800 ~ 1100 °C and their morphological and mechanical properties were analyzed. All properties before and after annealing were compared in order to study the thermal annealing effect on mechanical properties. The annealing process at high temperature led to the crystallization of the STS:TiCxNy and increased the grain size, which was confirmed by FE-SEM analysis. Micro-hardness value was 750 MHV at 800 °C and reached its maximum value of 918 MHV at 1000 °C, respectively. A heights corrosion resistance property was observed for the samples annealed at 1100 °C. Overall, composites with micro TiCxNy after high temperature annealing show improved properties compared to as sintered composites, making it possible to be utilizes in fuel cell.
